The oxygen incorporation/extraction kinetics of the potential solid oxide fuel cell (SOFC) cathode material Bi1−xSrxFeO3−δwith x= 0.5 and 0.8 was studied by electrochemical impedance spectroscopy on geometrically well-defined pore-free thin film electrodes. The oxygen exchange rate was found to be higher than that of La1−xSrxFeO3−δand—among cobalt-free perovskites—only surpassed by Ba1−xSrxFeO3−δwhich is however known to be unstable in a SOFC environment.
